title: 3D/4D sonographic evaluation of amniotic band syndrome in early pregnancy: a supplement to 2D ultrasound.
abstract: We present two cases of amniotic band syndrome diagnosed using two-dimensional (2D) ultrasound with three-dimensional (3D)/four-dimensional (4D) ultrasound in early pregnancy. In Case 1, at 13 weeks' gestation, multiple amniotic bands, acrania, the absence of fingers and amputation of the toes bilaterally were clearly shown using transvaginal 3D/4D ultrasound. In Case 2, at 15 weeks' gestation, several amniotic bands, acrania and a cleft lip were depicted with transabdominal 3D/4D ultrasound. The spatial relationship between the amniotic bands and the fetus was clearly visualized and easily discernible by 3D/4D ultrasound. The parents and families could readily understand the fetal conditions and undergo counseling; they then choose the option of termination of pregnancy. 3D/4D ultrasound has the potential to be a supplement to conventional 2D ultrasound in evaluating amniotic band syndrome.
